Introduction:

Traditional cloud security scanners excel at identifying isolated misconfigurations—public storage buckets, overly permissive IAM roles, or open security groups. While useful, these point-in-time findings fail to capture the reality of modern cyberattacks: adversaries rarely exploit a single weakness. Instead, they chain together seemingly minor misconfigurations to traverse cloud environments, escalate privileges, and exfiltrate sensitive data. SkullMap addresses this gap by shifting the paradigm from vulnerability discovery to attack chain intelligence. It maps the entire adversarial path across GCP, AWS, Azure, Oracle Cloud, and Kubernetes, using AI to narrate the attacker’s story, quantify financial impact, and simulate breach scenarios—all from a single open-source tool.

Learning Objectives & Secrets:

  • Objective 1: Master Attack Chain Discovery Across Multi-Cloud Environments. Learn to map interconnected misconfigurations across GCP, AWS, Azure, Oracle Cloud, and Kubernetes into visual kill chains that reveal the full adversarial path, not just isolated findings.

  • Objective 2 Secret Tip: Leverage AI-Powered Attacker Narratives for Deeper Insight. Use the `–ai` flag to generate human-language attacker stories. Combine `–persona apt` to simulate an Advanced Persistent Threat perspective, revealing how sophisticated adversaries think and operate—a perspective most scanners completely miss.

  • Objective 3 Secret Tip: Quantify Breach Economics and Optimize Fixes. Enable `–economics` to see the financial ROI of each attack chain from the attacker’s viewpoint. Use `–optimize` to identify the single fix that disrupts the maximum number of attack chains, prioritizing remediation efforts for maximum security impact.

skullmap auth-test --project my-gcp-project

AWS - checks public S3 buckets, EC2 metadata, Lambda URLs, and Cognito
skullmap auth-test --region us-east-1

Azure - checks public Blob storage, App Services, and Key Vault
skullmap auth-test --subscription my-azure-subscription-id

2. Sweep All Clouds Simultaneously:

skullmap auth-test --project my-gcp --region us-east-1 \
--subscription my-azure-sub --tenancy my-oracle-tenancy --all-clouds

3. What It Checks:

  • Public cloud storage buckets (GCS, S3, Azure Blob, OCI)
  • Unauthenticated Cloud Functions / Lambda / Azure Functions
  • Firebase Realtime Database open access
  • Cloud metadata servers (SSRF risk)
  • Exposed service account key files
  • Cognito self-registration misconfigurations
  • Key Vault / Secrets exposure
  • Exposed `.env` or credentials files in public storage

3. Advanced AI-Powered Analysis: From Data to Narrative

SkullMap’s AI capabilities transform raw scan data into actionable intelligence. The `–ai` flag generates a full attacker narrative in plain English, while `–predict` forecasts the attacker’s next moves.

Step‑by‑step guide:

1. Generate an Attacker Narrative:

skullmap scan --project my-gcp-project --ai

This produces a detailed, human-readable story of how an attacker would chain misconfigurations to compromise your environment.

2. Simulate Different Attacker Personas:

 Script Kiddie - basic automated attacks
skullmap scan --project my-gcp-project --ai --persona script_kiddie

APT - sophisticated, stealthy, long-term
skullmap scan --project my-gcp-project --ai --persona apt

Ransomware - immediate, destructive, profit-driven
skullmap scan --project my-gcp-project --ai --persona ransomware

3. Predict Next Attack Steps:

skullmap scan --project my-gcp-project --predict

This uses predictive AI to forecast the attacker’s next moves, enabling proactive defense.

4. Interactive AI Security Chat:

skullmap chat --project my-gcp-project

Engage in a conversational Q&A with an AI security consultant about your scan results and security posture.

4. Live Web Dashboard and Real-Time Monitoring

SkullMap includes a live web dashboard that visualizes scan results in real-time, eliminating the need for separate server setup.

1. Launch the Dashboard:

skullmap dashboard --project my-gcp-project

This opens an HTML dashboard directly in your browser from the `reports/` directory.

2. Enable Live Auto-Refresh:

skullmap dashboard --project my-gcp-project --live --interval 300

The dashboard automatically re-scans every 5 minutes (300 seconds) and updates with fresh findings.

3. Dashboard Metrics:

  • Overall risk score
  • Count of critical and high-severity findings
  • Number of active attack chains
  • Full attack chain visualization with paths
  • Recent findings table with severity
  • Live breach cost estimate
  • Zero Trust score (NIST SP 800-207)
